Question 1Basic Economic Concepts
In economics, the central problem of scarcity arises because:
- Businesses deliberately produce less than consumers demand
- Human wants are unlimited while productive resources are limited Correct answer.
- Some people choose to consume more than they can afford
- Governments restrict the supply of most consumer goods by law
Explanation
Scarcity is the fundamental condition in which wants exceed the resources available to satisfy them. Because land, labor, capital, and entrepreneurship are finite, every society must choose what to produce. Scarcity is not caused by legal restrictions or by individual overspending.
Question 2Basic Economic Concepts
A student gives up a $60 shift at work in order to attend a concert with a $40 ticket. What is the opportunity cost of attending the concert?
- $60, the wages that could have been earned
- $40, the price of the ticket
- $20, the difference between wages and ticket price
- $100, the ticket price plus forgone wages Correct answer.
Explanation
Opportunity cost is the value of the next best alternative forgone, measured in total. Attending the concert costs both the $40 paid for the ticket and the $60 of wages sacrificed by not working. Adding them gives $100.
Question 3Basic Economic Concepts
A production possibilities curve that bows outward (is concave to the origin) illustrates which principle?
- Zero opportunity cost for the first unit produced
- Decreasing opportunity cost as output expands
- Constant opportunity cost between the two goods
- Increasing opportunity cost as production shifts Correct answer.
Explanation
A bowed-out production possibilities curve reflects resources that are not equally suited to producing both goods. As more of one good is produced, increasingly less productive resources must be transferred, so each additional unit costs more of the other good. A straight-line curve would indicate constant opportunity cost.
Question 4Basic Economic Concepts
A point located inside a nation's production possibilities curve indicates that:
- The economy has achieved an unattainable combination of output
- The economy faces no tradeoff between the two goods
- The economy is producing beyond its productive capacity
- The economy is using resources inefficiently or has unemployed resources Correct answer.
Explanation
Points on the curve represent full and efficient use of available resources. A point inside the curve means the economy could produce more of at least one good without giving up any of the other, which signals inefficiency or unemployment.
Question 5Basic Economic Concepts
Which situation best describes a normative economic statement?
- A price ceiling set below equilibrium creates a shortage
- An increase in the minimum wage raises the unemployment rate among teenagers
- The unemployment rate fell to 4 percent last quarter
- The federal government should raise the minimum wage to reduce poverty Correct answer.
Explanation
Normative statements express value judgments about what ought to be and cannot be tested purely with data. The claim that the government should raise the minimum wage rests on a judgment about desirable outcomes. The other statements are positive claims that can be verified or refuted with evidence.
Question 6Basic Economic Concepts
The statement that an economy can produce more capital goods only by giving up some consumer goods reflects the idea of:
- An externality
- An incentive
- A tradeoff Correct answer.
- A market failure
Explanation
A tradeoff exists whenever gaining more of one thing requires sacrificing something else. Because resources are limited, devoting them to capital goods means fewer resources remain for consumer goods. Incentives, market failure, and externalities describe different concepts.
Question 7Basic Economic Concepts
A country can produce either 100 units of wheat or 50 units of cloth with its resources. What is the opportunity cost of one unit of cloth?
- 50 units of wheat
- 1 unit of wheat
- 2 units of wheat Correct answer.
- 0.5 units of wheat
Explanation
The opportunity cost of cloth is the wheat given up divided by the cloth gained. Producing 50 cloth costs 100 wheat, so each unit of cloth costs 100/50 = 2 units of wheat.
Question 8Basic Economic Concepts
Country A can produce a unit of rice using 2 labor hours, while Country B needs 6 labor hours. Which statement is correct?
- Neither country can benefit from trade in rice
- Country B has an absolute advantage in rice
- Country A has a comparative advantage only if Country B has an absolute advantage
- Country A has an absolute advantage in rice Correct answer.
Explanation
Absolute advantage means producing a good with fewer inputs. Country A uses 2 hours versus Country B's 6 hours per unit, so Country A is more efficient in absolute terms. Comparative advantage depends on relative opportunity costs, which this data alone does not establish.
Question 9Basic Economic Concepts
The law of comparative advantage implies that two nations can gain from specialization and trade when:
- One nation is more productive than the other in every good
- Each nation produces the good for which its opportunity cost is lower Correct answer.
- Both nations have identical opportunity costs for all goods
- Each nation produces the good for which it uses the fewest resources
Explanation
Comparative advantage is based on relative opportunity cost, not absolute productivity. Each nation gains by specializing in the good it can produce at a lower opportunity cost and trading for the other. Even a less productive nation can benefit if its relative cost is lower in some good.
Question 10Basic Economic Concepts
Which of the following is classified as a factor of production known as capital in economics?
- A factory building used to manufacture furniture Correct answer.
- A worker's years of job experience
- A share of stock purchased on an exchange
- Money held in a household savings account
Explanation
In economics, capital refers to produced goods used to produce other goods and services, such as machinery, tools, and factory buildings. Money and financial assets are not capital in this sense because they do not directly produce output. Job experience is a form of human capital, which is treated separately.
Question 11Basic Economic Concepts
Households supply labor, land, and capital to firms and receive wages, rent, and interest in return. This flow is best described by:
- The quantity theory of money
- The concept of a price floor
- The circular flow model of a market economy Correct answer.
- The law of diminishing marginal utility
Explanation
The circular flow model shows households supplying factors of production to firms through factor markets and receiving factor payments in return, while firms supply goods and services through product markets. It illustrates the interdependence of the two sectors.
Question 12Basic Economic Concepts
A market economy primarily answers the questions of what, how, and for whom to produce through:
- Central planning by a government agency
- Direct voting by citizens on each good produced
- Custom and tradition passed between generations
- Decentralized decisions guided by prices and self-interest Correct answer.
Explanation
In a market economy, prices coordinate the independent decisions of buyers and sellers pursuing their own interests. Prices signal scarcity and direct resources toward their most valued uses. Central planning and tradition characterize command and traditional economies.
Question 13Basic Economic Concepts
An economy that combines private ownership and markets with significant government regulation and public provision is best described as:
- A traditional economy
- A pure command economy
- A pure market economy
- A mixed economy Correct answer.
Explanation
A mixed economy blends market allocation with government intervention such as regulation, taxation, and public goods provision. Most modern economies, including the United States, are mixed. Pure command and pure market economies are theoretical extremes.
Question 14Basic Economic Concepts
The three fundamental economic questions that every society must answer are:
- Who should pay taxes, how much, and when
- How much to save, how much to invest, and how much to export
- What to produce, how to produce it, and for whom to produce it Correct answer.
- When to produce, where to produce, and why to produce
Explanation
Because resources are scarce, every economy must decide which goods and services to make, which techniques and resources to use, and how output is distributed among members of society. These three questions define the allocation problem.
Question 15Basic Economic Concepts
A technological improvement that raises output per worker will cause a nation's production possibilities curve to:
- Shift inward
- Become a straight line
- Remain unchanged
- Shift outward Correct answer.
Explanation
An outward shift of the production possibilities curve represents an increase in productive capacity. Better technology allows more output from the same resources, expanding the set of attainable combinations. Inward shifts occur when capacity is lost.
Question 16Basic Economic Concepts
If a nation devotes more resources to producing capital goods rather than consumer goods today, the most likely long-run result is:
- No change in future output
- Faster growth of the production possibilities curve over time Correct answer.
- A permanent reduction in productive capacity
- An immediate rise in current consumption
Explanation
Capital goods are used to produce other goods, so investing in them raises future productive capacity. Sacrificing current consumption shifts the production possibilities curve outward over time. Current consumption falls in the short run, not rises.
Question 17Basic Economic Concepts
The marginal benefit of an activity is best defined as:
- The average benefit per unit of the activity
- The additional benefit from one more unit of the activity Correct answer.
- The benefit given up by choosing an alternative
- The total benefit received from all units combined
Explanation
Marginal analysis focuses on the change in benefit from a small, typically one-unit, increase in an activity. Rational decision makers compare marginal benefit with marginal cost. Total and average benefit are different measures.
Question 18Basic Economic Concepts
A firm finds that producing one additional unit adds $30 to revenue and $25 to cost. According to marginal analysis, the firm should:
- Not produce the additional unit because cost is positive
- Reduce output because average cost is rising
- Produce the unit only if total revenue exceeds total cost
- Produce the additional unit because marginal benefit exceeds marginal cost Correct answer.
Explanation
Rational decisions compare marginal benefit with marginal cost. Here the marginal benefit of $30 exceeds the marginal cost of $25, adding $5 to profit, so the unit should be produced. Total and average measures are not the decision criterion.
Question 19Basic Economic Concepts
Which of the following is a positive incentive for a worker to supply more labor hours?
- A reduction in employer-provided benefits
- A higher income tax rate on wages
- A higher hourly wage rate Correct answer.
- A longer commute to the workplace
Explanation
An incentive is a reward or penalty that influences behavior. A higher wage raises the reward for working an additional hour, encouraging more labor supply. Higher taxes, longer commutes, and reduced benefits all act as disincentives.
Question 20Basic Economic Concepts
A government offers a subsidy to firms that install solar panels. The most direct effect of this policy is to:
- Raise the price firms pay for solar panels
- Reduce the quantity of solar panels demanded
- Eliminate the opportunity cost of installing panels
- Increase the incentive for firms to install solar panels Correct answer.
Explanation
A subsidy lowers the effective cost to the firm of taking an action, strengthening the incentive to do it. It typically increases the quantity of solar panels demanded rather than reducing it. Opportunity cost remains because resources are still used.
Question 21Basic Economic Concepts
A bakery can produce either 40 cakes or 80 pies per day. What is the opportunity cost of one cake?
- 2 pies Correct answer.
- 40 pies
- 0.5 pies
- 1 pie
Explanation
The opportunity cost of a cake is the pies given up divided by the cakes gained. Producing 40 cakes costs 80 pies, so each cake costs 80/40 = 2 pies. The reciprocal, 0.5 cakes per pie, answers a different question.
Question 22Basic Economic Concepts
Two nations each produce only two goods. Nation X gives up 3 units of good A to produce one unit of good B, while Nation Y gives up 5 units of good A to produce one unit of good B. Which statement is correct?
- Nation X has a comparative advantage in good B Correct answer.
- Nation X has a comparative advantage in good A
- Neither nation can gain from specialization
- Nation Y has a comparative advantage in good B
Explanation
Comparative advantage in good B belongs to the nation with the lower opportunity cost of producing it. Nation X sacrifices only 3 units of good A per unit of good B, compared with Nation Y's 5 units. Nation Y therefore has the comparative advantage in good A, and mutual gains from specialization are possible.
Question 23Basic Economic Concepts
Which statement about the production possibilities curve is correct?
- Points on the curve represent productive efficiency, and points outside are unattainable with current resources Correct answer.
- Points on the curve represent unemployment, and points outside are efficient
- Points inside the curve are unattainable, and points outside represent efficiency
- All points on the curve have the same opportunity cost
Explanation
The production possibilities curve shows the maximum attainable combinations given current resources and technology, so points on it are efficient and points beyond it cannot be reached. Points inside reflect inefficiency or unemployment. Opportunity cost varies along a bowed curve.
Question 24Basic Economic Concepts
A nation's production possibilities curve shifts outward after a large wave of immigration increases the labor force. Which statement best explains this shift?
- The economy has moved from an inefficient point to an efficient point
- The economy's opportunity cost of both goods has fallen to zero
- The economy now produces beyond its previous capacity without using additional resources
- The economy has more labor, a factor of production, so it can produce more of both goods Correct answer.
Explanation
An increase in a factor of production such as labor raises the economy's capacity to produce, shifting the entire curve outward. This is a change in the frontier itself, not a movement along it. Opportunity cost does not become zero when resources increase.
Question 25Basic Economic Concepts
A student decides to study for two more hours before an exam. Which reasoning best reflects marginal analysis?
- The student weighs the extra expected score gain against the value of the activities given up Correct answer.
- The student compares the total study time with the total hours slept this semester
- The student studies until total study time exceeds total leisure time
- The student studies because studying has always been expected of students
Explanation
Marginal analysis compares the additional benefit of a little more of an activity with its additional cost. The student considers the extra score improvement against the forgone value of alternative activities. Comparing totals or relying on custom does not apply the marginal rule.
Question 26Basic Economic Concepts
In economics, the concept of scarcity means that:
- Firms must pay wages to workers in order to produce output
- Human wants are unlimited while the resources available to satisfy them are limited Correct answer.
- Some people are poor while others are wealthy
- Governments must collect taxes to fund public goods
Explanation
Scarcity is the fundamental condition that human wants exceed the limited resources available to satisfy them. It is not about poverty, wages, or taxes specifically, but about the imbalance between unlimited desires and finite resources.
Question 27Basic Economic Concepts
Which of the following best describes the economic concept of opportunity cost?
- The additional cost incurred by producing one more unit of output
- The value of the next best alternative that is given up when a choice is made Correct answer.
- The total cost of producing a good, including fixed and variable costs
- The money price paid for a good or service
Explanation
Opportunity cost is the value of the next best alternative forgone when a decision is made. It is not necessarily a monetary price, nor is it total production cost or marginal cost.
Question 28Basic Economic Concepts
A production possibilities curve that is bowed outward (concave to the origin) reflects:
- Increasing opportunity costs as more of a good is produced Correct answer.
- Decreasing opportunity costs as more of a good is produced
- Constant opportunity costs as production of either good increases
- Zero opportunity costs for the first units produced
Explanation
A bowed-out production possibilities curve indicates that resources are not perfectly adaptable, so producing additional units of one good requires giving up increasingly larger amounts of the other good. This is the principle of increasing opportunity cost.
Question 29Basic Economic Concepts
In a circular flow model of a market economy, which of the following correctly describes a flow?
- Banks supply loans to households and receive interest payments from firms
- Firms supply goods and services to households in exchange for revenue
- Households supply factors of production to firms and receive income payments Correct answer.
- Governments supply public goods to firms without any corresponding payment
Explanation
In the circular flow model, households own factors of production and supply them to firms, receiving wages, rent, interest, and profit in return. Firms then use these factors to produce goods and services sold to households.
Question 30Basic Economic Concepts
Which of the following is an example of a positive economic statement?
- An increase in the minimum wage will cause some workers to lose their jobs Correct answer.
- The rich ought to pay a larger share of their income in taxes
- The government should increase spending on education to improve productivity
- Unemployment benefits are too generous and should be reduced
Explanation
A positive statement is a factual claim that can be tested against evidence, such as the predicted effect of a minimum wage increase on employment. Normative statements express value judgments about what should be done.
Question 31Basic Economic Concepts
A country can produce either 200 units of good X or 100 units of good Y with its given resources. What is the opportunity cost of producing one unit of good X?
- 1 unit of good Y
- 0.5 units of good Y Correct answer.
- 2 units of good Y
- 100 units of good Y
Explanation
The opportunity cost of one unit of X is the amount of Y given up. Since producing 200 X requires giving up 100 Y, each unit of X costs 100/200 = 0.5 units of Y.
Question 32Basic Economic Concepts
If a nation's production possibilities curve shifts outward, which of the following could explain this?
- A reduction in the quantity of capital goods available
- A decrease in the unemployment rate from 10% to 5%
- A shift in consumer preferences toward one of the goods
- An improvement in technology that raises output per worker Correct answer.
Explanation
An outward shift of the production possibilities curve represents economic growth, which can be caused by an increase in resources or an improvement in technology. A change in unemployment or preferences moves the economy to a different point on or inside the existing curve, not the curve itself.
Question 33Basic Economic Concepts
Which of the following is considered a capital resource in economics?
- A government bond held by a household
- A share of stock in a corporation
- A deposit in a savings account
- A delivery truck used by a business Correct answer.
Explanation
In economics, capital refers to produced goods used to produce other goods and services, such as machinery, equipment, and buildings. Financial assets like stocks, bonds, and deposits are not capital resources because they do not directly produce output.
Question 34Basic Economic Concepts
Suppose a firm's marginal benefit from hiring an additional worker is $500 per day, while the marginal cost is $400 per day. According to marginal analysis, the firm should:
- Hire the worker only if total profit is already positive
- Hire the worker because marginal benefit exceeds marginal cost Correct answer.
- Not hire the worker because the marginal benefit is greater than the marginal cost
- Not hire the worker because the marginal cost is positive
Explanation
Marginal analysis compares the additional benefit and additional cost of a decision. If marginal benefit ($500) exceeds marginal cost ($400), hiring the worker adds $100 to profit, so the firm should hire.
Question 35Basic Economic Concepts
A farmer can produce either 100 bushels of corn or 50 bushels of soybeans on a fixed plot of land. What is the opportunity cost of producing one bushel of soybeans?
- 0.5 bushels of corn
- 2 bushels of corn Correct answer.
- 50 bushels of corn
- 1 bushel of corn
Explanation
To produce 50 bushels of soybeans, the farmer gives up 100 bushels of corn. Therefore, each bushel of soybeans costs 100/50 = 2 bushels of corn.
Question 36Basic Economic Concepts
Two countries, Alpha and Beta, each produce only two goods: cars and computers. Alpha can produce 10 cars or 20 computers per day. Beta can produce 15 cars or 45 computers per day. Which statement about comparative advantage is correct?
- Beta has a comparative advantage in computers Correct answer.
- Alpha has an absolute advantage in both goods
- Beta has a comparative advantage in cars
- Alpha has a comparative advantage in computers
Explanation
Beta's opportunity cost of one computer is 15/45 = 1/3 car, while Alpha's is 10/20 = 1/2 car. Since Beta gives up fewer cars per computer, Beta has a comparative advantage in computers. Alpha has the comparative advantage in cars (opportunity cost of 2 computers versus Beta's 3 computers).
Question 37Basic Economic Concepts
A point inside a nation's production possibilities curve indicates that:
- The nation is using its resources efficiently
- The nation is producing beyond its capacity
- The nation has a comparative advantage in both goods
- Some resources are unemployed or used inefficiently Correct answer.
Explanation
Points inside the production possibilities curve represent inefficient use of resources, such as unemployment or underemployment. Points on the curve are efficient, and points outside are unattainable with current resources and technology.
Question 38Basic Economic Concepts
Which of the following best illustrates the concept of marginal thinking?
- A student decides to study because all of their friends are studying
- A student decides to study because education is valuable in general
- A student decides to study because their parents require it
- A student decides to study for one more hour because the expected benefit of the additional hour exceeds its cost Correct answer.
Explanation
Marginal thinking involves comparing the additional benefit and additional cost of a small change in behavior. Studying one more hour because its extra benefit exceeds its extra cost is a marginal decision.
Question 39Basic Economic Concepts
A government removes a tax on a good, which lowers its price. According to the law of demand, all else equal, the quantity demanded of the good will:
- Increase Correct answer.
- Remain unchanged
- Decrease
- Become perfectly inelastic
Explanation
The law of demand states that, all else equal, quantity demanded moves inversely with price. A lower price increases quantity demanded, which is a movement along the demand curve.
Question 40Basic Economic Concepts
A nation decides to devote more of its current resources to producing capital goods rather than consumer goods. The most likely long-run effect is:
- No change in either current or future production possibilities
- A lower current standard of living but faster future growth Correct answer.
- A higher current standard of living but slower future growth
- An immediate outward shift of the production possibilities curve
Explanation
Producing more capital goods means sacrificing current consumption, which lowers the current standard of living. However, the additional capital increases future productive capacity, shifting the production possibilities curve outward more rapidly over time.
Question 41Measurement of Economic Performance
A country's nominal GDP rises from $500 billion to $550 billion in one year, while the GDP deflator rises from 100 to 110. What happened to real GDP?
- It decreased by about 10 percent.
- It fell to zero.
- It increased by about 10 percent.
- It stayed exactly the same. Correct answer.
Explanation
Real GDP equals nominal GDP divided by the deflator, times 100. Here $550 billion divided by 1.10 equals $500 billion, matching the prior year, so real output was unchanged while only prices rose.
Question 42Measurement of Economic Performance
Which item is excluded from the calculation of GDP for the current year?
- A used car sold by a dealer to a student Correct answer.
- A consulting fee paid to a lawyer
- A haircut purchased at a salon
- A newly built house sold to a family
Explanation
GDP counts only goods and services produced during the period. A used car was produced in an earlier year, so its resale is excluded, though the dealer's service fee for the sale would count.
Question 43Measurement of Economic Performance
A national statistics office counts the value of intermediate goods separately from final goods when computing GDP. What error does this create?
- It converts GDP into net national product.
- It has no effect because intermediate goods net to zero.
- It understates GDP because final goods are ignored.
- It double-counts output and overstates GDP. Correct answer.
Explanation
GDP measures the market value of final goods and services, and the value of intermediate goods is already embedded in final prices. Adding intermediate goods separately counts the same production twice and inflates the total.
Question 44Measurement of Economic Performance
A worker who is laid off and has spent four months actively searching for a new job is classified as:
- structurally unemployed
- not in the labor force
- employed part-time
- frictionally unemployed Correct answer.
Explanation
Frictional unemployment reflects the short-run search time between jobs, and active search means the person counts as unemployed rather than out of the labor force. Structural unemployment instead reflects a mismatch of skills or location with available jobs.
Question 45Measurement of Economic Performance
The labor force consists of 160 million people, of whom 152 million are employed. What is the unemployment rate?
- 95.0 percent
- 8.0 percent
- 5.0 percent Correct answer.
- 5.3 percent
Explanation
The unemployment rate equals unemployed persons divided by the labor force, times 100. With 160 minus 152 equal to 8 million unemployed, 8 divided by 160 equals 0.05, or 5.0 percent.
Question 46Measurement of Economic Performance
Which situation best illustrates structural unemployment?
- An accountant takes a month off before starting a new position.
- A construction worker is idle during a winter slowdown.
- A recent graduate spends two months searching for a first job.
- A textile worker loses a job when the plant relocates abroad permanently. Correct answer.
Explanation
Structural unemployment arises when the skills or location of workers no longer match available jobs, as when an industry permanently relocates. The mismatch persists even in strong labor markets and requires retraining or relocation.
Question 47Measurement of Economic Performance
An economy has 10 million unemployed workers and 140 million employed workers. What is the unemployment rate?
- 6.7 percent Correct answer.
- 14.0 percent
- 10.0 percent
- 7.1 percent
Explanation
The labor force is 10 million plus 140 million, or 150 million. Dividing 10 million unemployed by 150 million gives 0.0667, so the unemployment rate is about 6.7 percent.
Question 48Measurement of Economic Performance
Which person is counted as out of the labor force?
- A teacher on unpaid leave who expects to return
- A machinist laid off last month who is applying for jobs
- A student working ten hours a week for pay
- A retiree who does not want a job Correct answer.
Explanation
People are outside the labor force if they are neither employed nor actively seeking work, as with a retiree who does not want a job. The labor force includes everyone working and everyone actively looking for work.
Question 49Measurement of Economic Performance
The consumer price index rises from 200 to 210 over a year. What is the inflation rate?
- 10.0 percent
- 2.0 percent
- 21.0 percent
- 5.0 percent Correct answer.
Explanation
The inflation rate is the percentage change in the price index, computed as the change divided by the starting value times 100. Here 10 divided by 200 equals 0.05, so prices rose 5 percent.
Question 50Measurement of Economic Performance
Suppose the market basket costs $400 in the base year and $460 in the current year. What is the consumer price index for the current year?
- 460
- 115 Correct answer.
- 60
- 87
Explanation
The CPI divides the current cost of the basket by the base-year cost and multiplies by 100. Thus $460 divided by $400 equals 1.15, giving an index of 115.
